Threshing machine cylinder



Patented Oct. 18, 1938 UNITED STATES PATENT OFFICE 1 Claim.

This invention appertains to new and useful 1 improvements in threshing cylinders for threshing machines, and also to an improved concave therefor.

The principal object of the present invention is to provide a cylinder and concave wherein the usual brush carrying elements are capable of being removed and replaced whenever they become worn or defective.

Another important object of the invention is to provide a cylinder in concave which in cooperation will be more efficient than the conventional type now in general use.

These and various other important objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings:

Figure 1 represents a fragmentary side elevational view of a thresher with a portion broken away to disclose the cylinder.

Fig. 2 is an end elevational view of the cylinder.

Fig. 3 is a longitudinal sectional view on line 33 of Fig. 2.

Fig. 4 is an outside elevational view of one of the discs.

Fig. 5 is a cross sectional View of one of the brush units.

Fig. 6 is a perspective view of one of the channeled members.

Fig. '7 is a side elevational view of one of the brushes.

Fig. 8 is an enlarged detailed sectional view taken substantially on the line 8-8 of Fig. 2.

Referring to the drawings wherein like numerals designate like parts, it can be seen in Fig. 1, that numeral 5 generally refers to a thresher having the intake conveyor 6. Numeral I generally refers to the improved threshing cylinder, while numeral 8 generally refers to the improved concave cooperating with the cylinder.

The cylinder 1 is mounted on the shaft 9 and consists of a pair of discs l0l0, each of which is provided at its outer side and adjacent periphery with the depressions II, for the reception of the laterally disposed and apertured lugs I2, at the ends of the channel bars l3. As shown in Fig. 8, bolts I4 are disposed through the openings in the lugs l2 and openings in the discs I0 for securing the channeled members I3 is a position bridging the peripheral portions of the discs Ill.

The brush itself is shown in Fig. 7 and consists of the back l5 from which the wire bristles l6 project.

channeled bar l3 and machine screws The back I5 fits snugly into the employed and disposed through the bottoms of the channeled bars l3 and into the back I5 to secure the brushes in the channeled bars.

Numeral l8 denotes the grating of the concave and. to the ends of this grating l8 are secured channeled members of the type denoted by numeral 13 with disposed therein and secured in the brushes shown in Fig. 7 place as shown in Fig. 5. These brushes are made concave which are identical in construction with those on the cylinder to operate with the brushes on the cylinder in the threshing of grain.

While the foregoing specification sets forth the invention in specific that numerous changes in it is to be understood the shape, size and.

terms,

materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:--

In a threshing machine, said threshing cylinder comprising a pair of a threshing cylinder,

diskshaped end members, said disk-shaped end members being formed with notches at their pemeans between the lugs and the end members,

and brushes disposed in the said channeled members.
